CAR-MAGNET SUPPORT.-

Application filed January 25, 1906- Berisl 110,297,745.

Be. it known that I, \VILLIAM MILTON BROWN, of Johnstown, Cambriacounty, Pennsylvania, have invented a new and useful Improvement inCar-Magnet Supports, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawin s, formingpart of this specification, iniwhic l- Figure 1 is a plan view showingmy invention as applied to a pair of car-trucks with theparts in thepositions which the; assume when thetrucks are passing aroum a curvein'gindicated in dotted lines. F ig; :2 is a of the magnet-support. Fig. 3is'a side view of Fig. 2. Fig. 4-is a section on the line IV IV of Fig.2, and Fig. 5 is a section on the line 1 VV-of-FigLQ; I 1

My invention has relat-ion to magnet-sup contact electric railways inwhich the circuitclo'sing magnets are carried by' the cars. In railwaysof, this class it is very desirable that the contact boxes or studswhich are embedded in the track shall be arranged at the center of thetrack-that is, midway between the track-rails' at all points'as well oncurves,

has been possible where single-truer cars carried on the trucks that thelongitudinal center of the ma net-support will at all times be'approxim'at y over the center of the not been heretofore possible,owing to the fact that the magnet-support must extend from one truck tothe other, andprior tomy invention no method has been devised, insocould be connected to the trucks in such a m e the support t iatitwill maintain prai.

far as I am aware, by which the support 1 manner as to maintain itsproper relation to 1 the trackcenter m passing around curves. The ob ectof my invention is to acCQmpllSh this resu t in a simple manner and toso a i tic ly the same position on a double-t ue I car as if it werecarried bet-ween the axles of a mum tract-ion typ the truckrames invarious wa s. -The frame of a double-truck car. -In the form shown 60these trucks are of the lwell-knou n maxie. 4 4designates't e lonitudinal frame, fromwhich are supported the depending circuit- Patented.M 19, 1907.

L' Tocarry the frame 4, qtrucks at a point between the bolsterjcenters Iprovide each of the with a transverse.supporting-bar 7 In the particularform of my invention illustrated the bar 7,issecured atits ends to sidebars 8, wh ch extend over the'journal-boxes 9 of the axle'2 and aresecured to the journal-box adjacent to the uides 10 and are thencecarsried downwar y and rear'wardly underneath the journal-boxes'l 1- of theaxles 3 and are secured to the joumal-box adjacent to the guides '12thereof. By this constructionv I provide a secure support for theoverhan am]; but it will be obvious that such are or their e uivalentmay be supported from 4 is pivotally'connected to t e central 01'- tionof each of the bars 7 b a pin or stu 13, as best shown in Fig. 4, t eframe 4 having oblong slots 14 to receive such pins'or studs, suitab ebearing-plates 15 being also interposed between said frame and bars-..

The broken line a a in Fig. l-indicatesthe longitudinal center of thecar-body in passing around the track-curve'shown, the center of suchcurve being indicatedby the broken line 'b b. Thebroken line a cindicates the center of the magnet-supporting frame 4. By an examinationof these center lines it will be noted that in passing around the itrack-curve shown the center line of the magnet-support has shifted withrespect to the center line of the car-body an amount equal to thedistance between the lines a a and c s, but that the center line of themagnet-frame maintains a substantial coinci- With this object in view myinvention coni deuce, with the center line of the track. slsts in thenoyel constructlon, arrangement, I This coincidence is not of course anexact one; and comb nat on of parts, all substantiallyas l but thevariation is so slight at any point in the length of the car-magnets asto be practi cally negligible. This position of the magnet-frame 1sassumed by reason of the pivot connections at 13, the elongated slots 14taking care of the variatiou'in the longitudinal distance between thecenters .of the bar 7' at different points of the curve and upon curvesin any position which the frame can assume.

As above indicated, the support which carries the centers 13 may beconstructed and arranged in various ways to correspond to diilerences inthe construction of the various kinds of trucks which maybe employed inany case.

What I claim is-% 1. The combination with the trucks of a double-truckcar, of a magnet-supporting frame extending, between the trucks andpiv-.

otally connected thereto at points between the bolstercenters; saidframe having extennets mounted on such extensions and also on sionsbeyondits' pivotal points, alnd magthe frame between the pivots,substantially as described.

2. The'combination with the trucks of a double-truck .car, of amagnet-supporting f-Jame extending between the trucks and pivotedthereto at points between the bolster centers, said supporting-framebeing independent of the car-body; said frame having extensions beyondits pivotalpoints, and

magnets mounted on such extensions and also on the frame between thepivots substantially as described.

3. The combination with the trucks of'a. double-truck car. said truckshaving overhanging or projecting supports extending between the trucks,of a magnet-supporting frame pivotally connected to the support of eachtruck; said frame having extensions beyond its pivotal points, andmagnets mounted on such extensions and also entire frame between thepivots substantially as described. i e

4.' The combination with the trucks of a double-truck car, said truckshaving supporting members extending between the trucks, of amagnet-supporting frame pivotallyconnected to each of said supportingmembers at points between the truck-bolsters and on the center lines ofthe trucks; said frame having extensions beyond its pivotal points; and

'magnets mounted on such extensions and also on the frame between thepivots, sub: stantially as described.

5. A car-truck having, side frame,- a supporting-b ar carried by thesaid frames, and a magnet-supporting frame pivotally connect-- ed to thesaid bar, at a point on the line of the truck and distant from thebolster center said frame having extensions beyond its pivotal points,and magnets mounted on such extensions and also on the'frame be tweenthe pivots, substantially as described.

6. The combination with the trucks of; a

double-trucl car, of a magnet-supporting frame extending between thetrucks and hav-' ing a; pivotal and slotted connection therewith atpoints between the bolster centers; said frame having extensions beyondits pivotal points, and magnets mounted on such extensions and also onthe frame between the pivots substantially as described. a

7. The combination with the trucks of a double-truck car, said truckshaving; over hanging or projecting supports extending between the trucksand carried by the" caraxles independently of the trucleframe, of amagnetsupporting frame pivoted to the end bars of such supports, atpoints between the bolster centers and having magnet-carrying extensionsbeyond its pivotal points; substantially as described.

- In testimony whereof I have hereunto set my hand.
